摘要:
Various embodiments of the present invention provide circuits and methods for improved FET matching. As one example, such methods may include providing two or more transistors. Each of the transistors includes a channel that varies in cross-sectional width from the source to the drain, and the transistors are matched one to another.
摘要:
The present inventions are related to systems and methods for pre-equalizer noise suppression in a data processing system. As an example, a data processing system is discussed that includes: a sample averaging circuit, a selector circuit, an equalizer circuit, and a mark detector circuit. The sample averaging circuit is operable to average corresponding data samples from at least a first read of a codeword and a second read of the codeword to yield an averaged output based at least in part on a framing signal. The selector circuit is operable to select one of the averaged output and the first read of the codeword as a selected output. The equalizer circuit is operable to equalize the selected output to yield an equalized output, and the mark detector circuit is operable to identify a location mark in the equalized output to yield the framing signal.

A clothing fabric for a paper machine has two or more endless strips, which are each formed by a film-like web spliced along a joint to form a film-like web that is endless in the direction of circulation of the fabric. The endless strips are connected to one another at the side edges with the joints of two endless strips that are connected to each other are arranged to be offset in relation to one another with respect to the direction of circulation of the fabric.

One aspect provides an optical communication system. The system includes an optical combiner, an optical tap, and a controller. The optical combiner is configured to receive a first optical signal at a first port of a plurality of ports. The optical tap is associated with the first port and is configured to divert a portion of the first optical signal. The controller is configured to monitor the diverted portion and to create an ID message including an identification datum associated with the port in the event that the diverted optical signal is detected.

Methods and systems are provided to allow personal computer users to virtualize a local audio device so that they can remotely connect to a server and interact with the server as if the local audio device was physically connected to the server. They connect a remote audio target hardware device to the target system through a physical USB connection, and the device interacts with the local user's computer over a network. The target system is unaware that the audio device is not connected directly to the system through a physical connection, and the target system does not need special software to implement the remote audio device. The audio target hardware device connected to the target computer may be physically connected and disconnected.

An apparatus and method for determining a resistance of a magneto-resistive head. A current drawn by the head, in response to a fixed bias voltage across the head, is converted to a zero temperature coefficient current such that when supplied to a resistor connected to an input terminal of a comparator the effects of variations in the resistance value are avoided. An output signal of the comparator indicates the resistance of the magneto-resistive head.

The invention relates to a method for performing network functions for a subscriber-sided (CPE) network access unit (ONT) in a telecommunication's access network with a central unit (CO, OLT), a distribution network (AN), and a multiple of network-sided network termination units (DPD) with subscriber-sided network access units (ONT) connected or connectable thereto, in which network a bidirectional communication path (1) is present between the central unit (CO) and that network-sided network termination unit (DPD), to which the subscriber-sided network access unit (ONT) under consideration is connected, in which for performing network functions a further bidirectional communication path (2) between the subscriber-sided network access unit (ONT) under consideration and the corresponding network-sided network termination unit (DPD) is used in connection with the bidirectional communication path (1) between the central unit (CO, OLT) and that network-sided network termination unit (DPD), as well as to a telecommunication's access network (FIG. 1), a central unit (CO, OLT), a network-sided network termination unit (DPD), and a subscriber-sided network access unit (ONT).
